Grapevine (Vitis vinifera L.) is the world's third most valuable horticultural crop, and the current environmental scenario is massively shifting the grape cultivation landscape. The increase in heatwaves and drought episodes alter fruit ripening, compromise grape yield and vine survival, intensifying the pressure on using limited water resources.

To test how ABA balances plant growth and environmental adaptation, we performed molecular genetics studies in the biotech crop Nicotiana benthamiana under well-watered or drought conditions. Studies on ABA signaling in crops are complicated by the multigenic nature of the PYR/PYL/RCAR ABA receptor family and its functional redundancy, which is particularly challenging in polyploid plants.

- The text discusses the necessity of developing genome editing technologies to identify key genes involved in how crops respond to environmental stress factors, particularly focusing on abscisic acid (ABA) receptors in plants.* -
- It highlights the challenges of working with polyploid plants due to their complex gene structures, specifically mentioning a biotechnological crop amenable to CRISPR/Cas9 techniques for analyzing its 23 ABA receptor family members.* -
- Results from the research showed that mutants lacking certain ABA receptors exhibited insensitivity to ABA in seed growth and development but maintained normal transpiration control, suggesting a strong regulatory system evolved from their harsh environmental origins.*
